An infinite parity function is a function : {,} {,} mapping every infinite binary string to 0 or 1, having the following property: if and are infinite binary strings differing only on finite number of coordinates then () = if and only if and differ on even number of coordinates.
Blum Blum Shub takes the form + =, where M = pq is the product of two large primes p and q.At each step of the algorithm, some output is derived from x n+1; the output is commonly either the bit parity of x n+1 or one or more of the least significant bits of x n+1.
For example, −4, 0, and 82 are even numbers, while −3, 5, 7, and 21 are odd numbers. ... The parity function maps a number to the number of 1's in its binary ...

For example, p 2 provides an even parity for bits 2, 3, 6, and 7. It also details which transmitted bit is covered by which parity bit by reading the column. For example, d 1 is covered by p 1 and p 2 but not p 3 This table will have a striking resemblance to the parity-check matrix (H) in the next section.
Define the parity vector function Q acting on as = = (()). The function Q is a 2-adic isometry . [ 27 ] Consequently, every infinite parity sequence occurs for exactly one 2-adic integer, so that almost all trajectories are acyclic in Z 2 {\displaystyle \mathbb {Z} _{2}} .
An example of problem in NC 1 is the parity check on a bit string. [6] ... The function mapping an input to a final state of the program is called the yield of the ...
Parity learning is a problem in machine learning. An algorithm that solves this problem must find a function ƒ, given some samples (x, ƒ(x)) and the assurance that ƒ computes the parity of bits at some fixed locations. The samples are generated using some distribution over the input.
